AVI is a container from the 1990s, and the DivX or Xvid video usually sitting inside it is why a camcorder tape rip or a decade old download will not play on a phone. Converting to MP4 swaps that aging codec for H.264 and leaves you a file modern devices treat as native. Old material often comes out smaller too, since compression has improved a great deal since AVI was fashionable.

Frequently asked questions

My AVI plays with no sound on my phone, does converting fix that?
Usually yes. These files often carry audio as AC3 or MP2, which mobile devices ignore, and the conversion re-encodes the soundtrack to AAC that everything supports.
Will my old low resolution video look worse?
Nothing is upscaled or sharpened, the frame size you had is the frame size you keep. A grainy 640 by 480 clip stays a grainy 640 by 480 clip, just in a wrapper that opens.
What about the interlacing on captured tapes?
Interlaced footage passes through as it is. Combing on fast motion came from the capture itself and needs a dedicated deinterlacing step, which this page does not do yet.
